# Effects in Bass audio library end prematurely

## Recommended Posts

Hi all,

I am making a program in which I use Bass audio library (with the wrapper for autoit that I found here on forums I think) because of its support for dx effects.

My problem, though, is that when effects as reverb or echo/delay are added, the channel length is not extended as to fit the tail of the effect, so if the file was really short, you wouldn't even hear the reverb at all.

I've tried setting the  buffer parameter even to 60k ms, updating the channel length to 60k ms, but nothing makes it so that the effects aren't being cut off.

I've heard that I could add silence manually to wave files by adding the chr(0) characters, but haven't had any luck doing that, either.

What I'm doing:

1. initialize bass
2. use streamCreateFile to load the wave file with the fx flag and length parameter set to 60000
3. set the config buffer to 60000
4. use channel set fx to add dx8 reverb
5. use channel play to play the sound
6. use bass update to update the length to 60000

I even tried having only silence in one wave file and tried joining two wave files together, but that didn't work either.

Any help would be very much appreciated.

This file includes the source code for zPlayer, which is a stand-alone, simple, intuitive and easy-to-use, yet fully functional media player.  I made this to suit my purpose and you can tweak it to your taste. The source code is only about 1600 lines and only standard #include files were used. Also included in the source code file are some image files which are used for drawing the graphical media controls in the main window.
As of its release date, the compiled exe file of this player, as attached hereto, is not flagged by Windows Defender with latest Security Intelligence Update.
Hash values for compiled file of the latest version are as follows:
SHA256: EF952C26961241CECF5EEB3E34CCACC369F9F158E71028BAFC36F86BA0B03C03
SHA1: 7F78EA91E069D1A6D646A6FBBB390EC68ABDED81

This player has the following features:
- Play back all formats of media files which can be played back by the Windows Media Player in your computer
- Depending on the file types specified by the user in zPlayer.ini file this player can be either audio only, video only or both.
- Video window is independent of other windows and, when maximized, increases the immersion of the user
- Graphical media controls similar to embedded Windows Media Player
- Forward, backward, pause, repeat, shuffle function
- Increase/decrease/mute sound volume
- Change folders and create playlist for all media files in that folder and its subfolders, and support for manually-made playlists
- Save play-back environment when terminating and resume that environment when restarting
- 'Continue playback' option for a file you left off in the middle of playback
- With one click, you can see internet search results for the file selected in playlist
- With a double-click, you can play back an item in the playlist
- Search strings in the playlist
- Option to see long file names including folder names
- View file properties for any file in the playlist and copy their values
- Resize the playlist and video windows, and restore them to their default positions
- Very small footprint: very low CPU and memory usage, with only about 1MB when compiled
- You can even hide all the windows and manipulate the player with hotkeys only
Note: zPlayer is the name I used when I introduced the early version of this player in my blog back in early 2009 and, therefore, has nothing to do with the mobile media player of the same name which started marketing in 2015.

After I retired from active duty in 2002 I spent much time listening to music. First I started with CD's and LP's, then quickly moved on to mp3 files. I converted many of my CD's to mp3 and I collected many more from various sources which were freely available at the time. As the number of my mp3 files grew, I put them in folders according to their genres and my favorite classifications. I mainly used Windows Media Player to listen to them and I slowly began to dislike wmp because it had massive user interface while I just wanted to listen to music in the background while I was doing other work in the foreground, hopping between folders from time to time. It was the time I was beginning to learn AutoIt and I thought I should make my own player with AutoIt. Coming from a sales career with no experience in programming, it was not an easy task. Somehow, after about 2 years of learning and trying, I had my own audio player which worked with only hotkeys without any graphical interface. I gave it to some of my friends who were not as computer-savvy as I. They liked it but definitely wanted something to clcik with mouse. So I came up with very rude gui which took a form similar to what it is now.
The attached source files include one au3 file, one icon file and 14 jpg files. The jpg files are used for drawing a graphical player and are fileinstalled in @DocumentsCommonDir folder. This player uses WMPlayer.OCX as its engine and supports all audio file formats supported by wmp and additional codecs installed. I would like to thank @Bilgus for kind answers to my questions and would appreciate it if anyone could review the code and give me any suggestion. This player works for me, but I don't know whether the code is presentable as an example. I am posting this here with a hope to learn much from AutoIt community.
PS: Video function was added in August 2020.

• Hi all,
My programming knowledge is very basic.
I have an old script that creates shares and assign permissions. It normally registers SetAcl.ocx if necessary and creates an object to assign permissions.
The command that registers SetAcl was apparently working fine under Windows 7 but is not working under Windows 10.
RunWait("regsvr32.exe path\to\setacl.ocx /s", "", @SW_HIDE) As I'm logged in as admin, I changed this command to :
RunAsWait(@UserName, "", "", 0, "regsvr32.exe path\to\setacl.ocx /s", "", @SW_HIDE) It seems to terminate correctly but the script still doesn't work as expected.
To check that, I've created that small script :
Local $objSetAcl = ObjCreate("SETACL.SetACLCtrl.1") If IsObj($objSetAcl) Then ConsoleWrite("Object successfully created." & @CRLF) Else ConsoleWrite("Object not created. Registering SetAcl.ocx" & @CRLF) Local $result = RunAsWait(@UserName, "", "", 0, "regsvr32.exe path\to\setacl.ocx /s", "", @SW_HIDE); Use of my admin username to elevate CMD ConsoleWrite("Return code : " &$result & @CRLF) ConsoleWrite("Creating object" & @CRLF) $objSetAcl = ObjCreate("SETACL.SetACLCtrl.1") If IsObj($objSetAcl) Then ConsoleWrite("Object successfully created." & @CRLF) Else ConsoleWrite("Object creation failed." & @CRLF) EndIf EndIf It tries to register SetAcl.ocx, return code 0 seems to be fine but still can't use SetAcl.
But if I go to CMD as admin, run the regsvr32 command and restart my script, it can create the object without issue.
I know my poor knowledge makes me miss something. Anyone can help me figure this out ?

• This topic give you access to an AutoIt functions library I maintain which is called PAL, Peter's AutoIt Library. The latest version 1.25 contains 212 functions divided into these topics:
window, desktop and monitor GUI, mouse and color GUI controls including graphical buttons (jpg, png) logics and mathematics include constants string, xml string and file string dialogues and progress bars data lists: lists, stacks, shift registers and key maps (a.ka. dictionaries) miscellaneous: logging/debugging, process and system info Change log and files section  on the PAL website (SourceForge).
A lot of these functions were created in the development of Peace, Peter's Equalizer APO Configuration Extension, which is a user interface for the system-wide audio driver called Equalizer APO.
